Natural deduction systems for some non-commutative logics

Norihiro Kamide, Motohiko Mouri
2007 Logic and Logical Philosophy  
Varieties of natural deduction systems are introduced for Wansing's paraconsistent non-commutative substructural logic, called a constructive sequential propositional logic (COSPL), and its fragments. Normalization, strong normalization and Church-Rosser theorems are proved for these systems. These results include some new results on full Lambek logic (FL) and its fragments, because FL is a fragment of COSPL.
